Flight activity of Melipona asilvai Moure (Hymenoptera: Apidae) [PDF]
Brazilian Journal of Biology, 2006 Many stingless bee species are specific to their areas of occurrence. Even when adapted to their local climate and flora conditions, they are subject to modifications in the environment, directly influencing flight activity. The aim of this work is to obtain information about the flight activity of the stingless bee Melipona asilvai Moure, thus ...

Longitudinal differentiation in Melipona mandacaia (Hymenoptera, Meliponini) chromosomes [PDF]
Hereditas, 2003 Melipona mandacaia is a stingless bee endemic to northeast Brasil. We describe the M. mandacaia karyotype using C-banding technique. fluorochrome staining and treatment with restriction enzymes and discuss the position of this species in the context of the phylogeny of the genus. Melipona mandacaia has 2n = 18 (14 SM + 2 M + 2 A).
